G'day marbu,

Welcome to the Monastery.

The code you posted was not the code that generated that error message. Please don't do that.

Most (if not all) of Tk's option/value pairs have a '-' before the option (e.g. -option => $value).

Your problem, in your real code, stems from writing pady, instead of -pady, in pack() (see Tk::pack).

Here's a working example:

$ perl -e 'use Tk; MainWindow->new()->Button(-text => "?")->pack(-pady
+ => 2); MainLoop'

Here's your error replicated:

$ perl -e 'use Tk; MainWindow->new()->Button(-text => "?")->pack(pady 
+=> 2); MainLoop'
bad option "pady": must be -after, -anchor, -before, -expand, -fill, -
+in, -ipadx, -ipady, -padx, -pady, or -side at /long/path/to/Tk/Widget
+.pm line 1217.
 at -e line 1.

Here's another example (with '-' omitted from the -text option in Button()):

$ perl -e 'use Tk; MainWindow->new()->Button(text => "?")->pack(-pady 
+=> 2); MainLoop'
unknown option "text" at /long/path/to/Tk/Widget.pm line 205.
 at -e line 1.

See also Tk::options.

By the way, you can completely ignore the first answer you got which talked about "unixisms" and suggested threads would fix the problem. This looks like trollage to me: I downvoted it.

But your code doesn't attempt to use Tk::ExecuteCommand on windows :/

"... your code doesn't attempt to use Tk::ExecuteCommand ..."

Of course not, that isn't the source of the reported error.

Yeah, unixisms arent portable

I would use threads instead, see

Re: Perl Tk nonblocking (threads queue), Capture::Tiny, Re: Tk with thread and stram data ( return )

I was wondering what "unixisms" you refered to and found in Tk::ExecuteCommand's source code this: open $h, $self->{-command} . ' 2>&1 |'; . Does anyone know if that's valid in win?

'2>&1 |' is valid in CMD.exe.

But the demonstrated pipe | should rather already be Perl syntax from open

Do you have windows? Get windows and try stuff

for me, the OPs program doesn't trigger the -tk -option -error -reported

Tk::ExecuteCommand however does not work

Can't stat /dev: No such file or directory
at ... Proc/ProcessTable.pm

Tk fileevent doesn't work on windows

Good morning and many thanks for the quick reply. Will try to test it the next days. Just like I said I'm totally new on perl programming and try to find a way through all the scripts here ath work. Thanks and have a great weekend. Markus

Thanks again for all your help.
Couldn't find a way through this problem. We now just use an older version of TK and it works. Just used in a small amount of scripts so we can ignore.
Have a great day.
Greetings Markus
